please make sure the right pcm_bluetooth plugin is loaded. It needs to
be installed in /usr/lib/alsa-lib. If you installed it with a different
prefix and it ends up in /usr/loca/lib/alsa-lib then it won't work. The
audio service needs to be used with the matching plugin.

This is a question for the ALSA guys. I really have no clue.

The audio service has been improved a lot of 3.26 and thus it might
simply miss a patch. However for me it is already too old to remember
any details.
